Check Digit Verification of cas no

The CAS Registry Mumber 75499-80-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,9 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75499-80:
(7*7)+(6*5)+(5*4)+(4*9)+(3*9)+(2*8)+(1*0)=178
178 % 10 = 8
So 75499-80-8 is a valid CAS Registry Number.
